Review on 🚗 Transform Your Ride with Timbren GMRYS4 Suspension Enhancement System: Advanced Performance and Comfort Guaranteed by Tim Rushing

I would highly recommend this product and will in fact buy it for every truck I have in the future. This upgrade is definitely worth the money. I replaced the rear bumpers on my 2000 GMC Yukon 2WD SLT with this Timbren GMRYS4 Suspension Upgrade System. I measured the "squat" and prior to the upgrade my suspension was 1 inch below normal height when I attached my aluminum three horse trailer which weighs about 3500 pounds. The normal height is 37 inches from the ground to the top of the wing. With the trailer attached, it dropped to less than 36 inches. After installing Timbren fenders, the height of the rear of my truck did not change. I was shocked. I knew it would help, but I didn't think it would help that much. Driving to the show fully loaded I'm about 6500lbs GCWR and now the squat is less than half an inch. And again I was surprised. But I used the same tape measure and the truck was parked in the same spot. As for the front end, I decided to replace it with Revain's cheaper options. One installation tip: after jacking up the truck, have one person lower the truck while a second person holds the Timbren fender in place. In my case you use the weight of the truck to push the rubber into the mount it is in. A bit of spray lube helped "snap" it in place. But when it's in place, it doesn't move and sits right over the frame when the trailer isn't connected. As far as driving on the road, it's like a new truck!
